JOHN W. LAMBERT, OF ANDERSON, INDIANA, ASSIGNOR TO THE BUCKEYE MANUFACTURING COMPANY, OF SAME PLACE.

MIXER AND VAPORI2ER FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent N 0. 660,778, dated October 30, 1900.

Application filed December 23, 1899. Serial No. 741,406. (No model.) i

T at whom it may concern;

Be it known that 1, JOHN W. LAMBERT, acitizen of the United States, and a resident of Anderson,in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Mixers and Vaporizers for Gas-Engines, of which the following is a full, clear, and exact description, reference being had therein to the accompanying to drawing.

In the drawing is represented an end view of a gas-engine cylinder having attached to it my device, the device being shown partly in section.

[5 The object of this invention is to provide an extremely simple and reliable device for thoroughly vaporizing and mixing gasolene or other volatile hydrocarbon with air for introduction into the explosion or igniting chamber of the working cylinder, as more fully hereinafter set forth.

Referring to the drawing by letters, A designates the cylinder of the engine; B, the explosion or igniting chamber attached to the end of the cylinder and communicating therewith; O, the inlet-valve normally seated over an opening in the bottom of the explosionchamber; D, a passage leading to the valveopeniug and extending laterally therefrom; E, a foraminous diaphragm, preferably con structed of several layers of Wire-gauze extending vertically across the lateral branch of said passage D, said passage being enlarged annularly at the point where said dia- 5 phragm is fixed; F, a vertical tubular mixingchamber connected to the lateral branch of passage D and having attached to its upper end a gasolene-cup G, having a sight-feed H, controlled by a suitable valve I,.so that the gasolene may be fed drop by drop into the mixing-chamber F, the feed being directly into the center of said chamber F, so that the gasolene will have an unobstructed fall clear through said chamber into a pipe J, 5 connected to the lower endof the chamber and depending therefrom, this pipe being provided with a lateral inlet K for air and at a point below said inlet K with a lateral outlet L for such gasolene as may fall below said inlet, this gasoleneoutlet being normally closed by an outward-opening valve M.

Asitis well understood,the valve Ois opened and the charge is drawn into the explosionchamber by the suction created by the piston in the cylinder. As will be observed, the air will be drawn in through inlet K, pipe J, chamber F, diaphragm E, and passage D, and that in its upward passage through chamber F it will meet the descending drops of liquid and forcibly disintegrate them and carry them in through diaphragm E, and thereby further comminute them and mix the fine spray or vapor thus produced with the air before introduction into the igniting-chamber. It will be observed that it is essential that the descending liquid shall fall in detached particles and that the particles shall have a clear fall against the upward-moving current of air, so that the liquid will be thoroughly broken up into fine particles before it is thrown violently through the foraminous diaphragm. It will also be observed that valve M is held tightly closed during the suction, but is free to open automatically at other times to discharge any gasolene that may have accumulated in the lower end of pipe J.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In combination, a gas-engine cylinder, an inlet-valve, a mixing-chamber connected thereto by a lateral passage, a feed device adapted to feed gasolene into the upper end of said mixing-chamber so that the gasolene will fall unobstructively through the same, an air-inlet pipe connected to said mixingchamber at. its bottom, directly beneath the feed device, so that the inward current of air will be directed upward against the falling gasolene and the unvaporized gasolene will fall directly into said air-pipe, and a pipe to carry off the unvaporized gasolene provided with an outwardly-opening valve adapted to be held closed by the suction.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 13th day of December, 1899.

JOHN W. LAMBERT.
